Abstract (en)
[origin: EP1283233A1] A polyoxyalkylene derivative is represented by formula (I) : <CHEM> wherein Z represents a residue of a compound having 2 to 8 hydroxyl groups; AO represents an oxyalkylene group having 2 to 18 carbon atoms; n and m each represent an integer of 0 to 2000 provided that both n and m do not represent 0; a and b each represent an integer satisfying the relationships; 2≤a+b≤8 and 1≤b; R represents a hydrocarbon group having 1 to 30 carbon atoms; and X represents a divalent hydrocarbon group having 3 to 10 carbon atoms.
